Practical handling of allergic reactions to COVID-19 vaccines

ConclusionAllergy testing is not necessary for the vast majority of allergic patients prior to COVID-19 vaccination with currently licensed vaccines. In case of allergic/anaphylactic reactions after vaccination, allergy workup is recommended, as it is for a  small potential risk population prior to the first vaccination. Evaluation and approval of diagnostic tests should be done for this purpose.
